Overview
The ALM2 provides alarm detection and reporting by monitoring up to eight inputs. Each input can be configured to
support a temperature reading using a thermistor or a dry contact reading.
Each alarm event detected is reported to the network. Digital outputs are provided to drive external alarm indication
such as lamps or buzzers.
The controller is based on the L
